Voice Pedal
From CCRMA Wiki
Project Idea
The Voice Pedal (in lieu of a better name) is an application for singers to modify their voice during live performance. The Voice Pedal includes several effects: Vocal Sustain, Reverb, Pitch Shift, and looping. The project will culminate in a composition designed to take advantage of the tools available.
